I just emerged world after some time out (note: i upgraded my system form an athlon64 to a core i7 2600k) and today after re-emerging thunderbird and firefox (emerge -uDNv world) they simply do not start. The exit code in shell is 1. i managed to find in a forum that i should have used the -mno-avx gcc switch. Reproducible: Always Actual Results: apps do not start NOTE: the emerge --info below work; deleting the "-mno-avx" switch in make conf do not allow ff and tb to start. emerge --info Portage 2.1.10.11

have you re-emerged world after hardware change?
This has already been addressed in {fx/tb}-6 please upgrade if you do not want to pass additional CFLAGS not found in ebuild.
@agostino: no, not world, but most packages, however i had no other issues @jory: ok, i might go ~amd64 on those, however maybe a notice in the ebuild could be helpful for other people stumbling in the same issue.
Francesco, if you have compiled your world with -march=native with amd processor, now you need emerge -e world, then you can post a bug.
Agostino, nope, after i did my hardware upgrade, i changed the make.conf to -march=native and re-emerged system; then, bit by bit i re-emerged other packages (specially when upgrading them). All went fine without a single problem. Today, upgrading world, firefox and thunderbird (that had not yet been recompiled) were emerged and they simply won't start. I found the issue discussed in the forums and the culprit seems to be (lack of) gcc switch -mno-avx (xulrunner? do not like avx instructions on sandy-bridge processors). Adding -mno-avx to make.conf and re-emerging ff and tb made them work. As Jory said this has been addressed in ff/tb-6.0 ebuilds. Maybe a warning in previous ebuilds would prevent some headaches :)
You have not explainet it before ;)
